Convert any dollar amount from 1913 onward into 2025 dollars using official Consumer Price Index data. Every page shows the index values and the arithmetic, so you can check the result rather than take it on trust.
A single dollar, adjusted forward to 2025 dollars.
The Consumer Price Index measures the average price of a basket of goods and services bought by urban households. To compare money across time, you take the ratio of the index in the two years and multiply:
The index used here is CPI-U — all urban consumers, US city average, all items — with base period 1982-1984 = 100. Annual averages are used throughout rather than a single month, which is why results can differ slightly from calculators that pick a specific month.
Two calculators can give different answers for the same question and both be defensible. The three usual causes: one uses a monthly index and the other an annual average; they use different end years; or one silently extends the index before 1913, where no official data exists. Every page on this site states both index values used, so the arithmetic can be reproduced.
Official BLS Consumer Price Index data begins in 1913. Figures for earlier years are reconstructed historical estimates rather than official statistics.
Reconstructed series exist — the Federal Reserve Bank of Minneapolis publishes one back to 1800, stitching together an index of prices paid by Vermont farmers (1800–1851), Ethel D. Hoover's consumer price index (1851–1890) and Albert Rees's cost of living index (1890–1912) onto modern BLS data. These are useful for historical context but are estimates rather than official statistics, so this site currently covers 1913 onward only.
Pick a starting year to convert any amount into 2025 dollars. Years before 1913 use a reconstructed index and are marked as estimates.
